A Data file is a computer file which stores data to be used by a computer application or system. It generally does not refer to files that contain instructions or code to be executed typically called program files , or to files which define the operation or structure of an application or system which include configuration files, etc.
This is especially helpful when debugging a program. Most computer programs work with files. This is because files help in storing information permanently. Database programs create files of information. Compilers read source files and generate executable files. A file itself is an ordered collection of bytes stored on a storage device like tape , magnetic disk , optical disc etc. A text file contains human-readable characters. A user can read the contents of a text file or edit it using a text editor.
In text files, each line of text is terminated, delimited with a special character known as EOL End of Line character. In text files some internal translations take place when this EOL character is read or written. A binary file is a file that contains information in the same format in which the information is held in memory i. In binary file, there is no delimiter for a line.
Also no translations occur in binary files. As a result,binary files are faster and easier for a program to read and write than the text files. As long as the file doesn't need to be read or need to be ported to a different type of system, binary files are the best way to store program information. Closed data file formats, frequently referred to as proprietary format files , have their metadata data elements hidden, obscured or unavailable to users of the file.
Application developers do this to discourage users from tampering with or corrupting the data files or importing the data into a competitor's application. Open data format files have their internal structures available to users of the file through a process of metadata publishing.
Metadata publishing implies that the structure and semantics of all the possible data elements within a file are available to users. From Wikipedia, the free encyclopedia.
